Answer:
Neurotransmitter
Explanation:
A neurotransmitter is a signal which transmits information between neurons at the end of the axon. This neurotransmitter can either be excitatory or inhibitory. Whenever an action potential is triggered within a neuron, the neurotransmitter releases this action potential into the synapses at the axon as either an excitatory or inhibitory signal before a new action potential is triggered.
Answer:
In the given case, it is clear that the sympathetic part of the autonomic nervous system is on in Mr. T. It can be suggested due to the increase in heart rate and appearance of cold and pale skin in the patient's upper body. The sympathetic nervous system is the component of the ANS, which is an extensive network of neurons that monitor's the involuntary processes of the body.
Mainly, the sympathetic nervous system monitors the features of the body associated with the fight or flight response like increasing heart rate, mobilizing fat reserves, and discharging adrenaline. Apart from this, the increased heart rate and vasoconstriction will assist in elevating the patient's blood pressure.
The intensity of light had greater impact on the rate of photosynthesis. It was observed that the jar in which the intensity of light was high, large amount of oxygen was produced as compared to the jar in which the intensity of light was low.
In the process of photosynthesis, oxygen is produced from the carbon dioxide. As the oxygen in the jar increases, the leaf disk rises with in the jar which also signifies the higher oxygen production with higher rate of photosynthesis in presence of high intensity of light.
